FEEDER.

Specification of Letters Patent.

Patented Dec. 14, 1920.

Application filed February 16, 1920. Serial No. 358,933.

To all whom it may concern Be it known that I, JAMES LEsLIn STEW- ART, a citizen of the United States, and a resident of Billingham in the county of VVhatcom and State of Vi ashington, have invented certain new and useful Improvements in Feeders, of which the following is a specification.

My invention is an improvement in feeders, and has for its object to rovide a feeder especially adapted for feeding boiler compounds, wherein the rate of feed is con trolled directly by the velocity of the feed water in the feed pipe.

In the drawin s:

Figure 1 is a rent view of the improved feeder;

Figs. 2 and 3 are sections on the lines 2-2 and 33, respectively, of Fig. 1.

In the present embodiment of the invention a suitable casing 1 is provided, having at its lower end a standard 2 which is connected with a casing 3 interposed in the feed pipe 4. This casing 3 is cylindrical and of greater diameter than the feed pipe, as shown, and at each end the casing has reduced portions 5 which are connected with the feed pipe by means of flanges 6 on the feed pipe and on the reduced portion. The flanges are connected by bolts and nuts 7.

The top of the casin 1 is closed and it has a filling funnel 8 at t e center of the top, whose communication with the casing is controlled by a valve indicated at 9. This funnel permits the casing to be filled with the solution to be fed to the pipe. The casing also has a glass gage 10 which permits the amount of compound in the casin to be determined at a glance, the gage being of the usual construction.

An inlet pipe 11 leads from the casing 3 to the top of the casing 1, and delivers into the casing at the top as shown. An outlet pipe 12 leads from the opposite side of the casing 1, and delivers to the casing 3 at the opposite end from the pipe 11, and this pipe 12 extends to near the bottom of the casing 1. A regulating valve, indicated at 13, is interposed in the length of the pipe 11 and a sight feed 14 and a cut-off valve 15 are interposed in the pipe 12.

Referring to Figs. 1 and 3, it will be seen that at its lower end each of the pipes 11 and 12 has a laterally extending flaring mouth 16, and that the said mouths face in opposite directions, the mouth of the pipe 11 facing the oncoming water in the feed pipe, while that of the pipe 12 faces the water which has passed.

A drain pipe 17 is provided for the casing l and this pipe is controlled by a trip valve 18 near the casing.

In operation, a boiler compound of suitable character is placed in the casing 1, by means of the feed funnel 8. When water is feeding, the regulating valve 13 being opened to the proper degree, in accordance with the amount of compound it is desired to feed, the valve 15 is also opened. The water flowing through the feed pipe will enter the mouth 16 of the pipe 11 and will travel up the said pipe and be delivered to the casing 1. This water is of lower specific gravity than the compound in the casing, and the incoming water will force the compound out through the pipe 12 and through the mouth 16 to the passing water, where the compound will be thoroughly mixed with the water. Regardless of the velocity of the water in the feed pipe the supply of compound will always be directly proportionate thereto.

It will be understood that the feeder may be used to feed a compound of hi her or lower specific gravity than water. 0 feed a compound lighter than water the feeder is arranged as shown in the sketch. To feed one heavier than water the device may be reversed. In the first case, the compound is lifted by the water, while in the second case the water is above the compound.

I claim:

A device of the character described comprising a horizontal casing interposed in a pipe line, a standard rising from said casing, a vertical casing mounted on said standard and provided with a filling opening, and a pair of diametrically opposite pipes leading from the top of the vertical easing into the horizontal casing near the ends thereof and terminating along the longitudinal center line thereof, the terminals within the horizontal casing being laterally deflected in opposite directions.
